高校图书馆不同功能定位下对音乐元素运用的思考

在高校图书馆传统功能定位下，音乐元素的融入受到了极大的限制。音乐及阅读心理治疗等新功能的设置，则将音乐元素更广、更深地融入到高校图书馆的工作中，可更好地为高校广大师生的学习生活提供服务。从高校图书馆传统功能定位下音乐元素的融入和高校图书馆新功能定位下音乐元素的融入两个方面，提出了高校图书馆不同功能定位下对音乐元素运用的思考。

多平台基于方位时延差的目标运动分析

以拖曳阵列与本舰所构成的声纳系统为例 ,从双平台观点考虑 ,利用对目标的两方位及时延的量测为依据 ,研究了该系统的目标运动分析 (targetmotionanalysis,TMA)问题。采用了最大似然估计、扩展Kalman滤波(EKF)方法 ,实现了对目标运动参数的估计 ,并给出了它们的Cramer Rao低界 (CRLB)。通过仿真考察了参数变化对估计精度的影响。仿真结果表明上述方法具有较高定位精度。该方法适合于主、被动形式的多平台系统 ,且容易实现。     

Relationship between the partitioning properties of motoneuron recruitment and the needle feeling propagation

Histological and physiological studies indicated that most skeletal muscles can be divided into a series of relatively independent sub-volumes: "neuromuscular compartments" and the partitioning property of the muscle result in the localization of muscle reflex. In the present experiment we studied the recruitment properties of medial gastracnemius (MG) muscle motoneuron pool of decerebrate cat with two kinds of local mechanical stimulation: local stretch and acupuncture-like stimuli. The results indicate that: (ⅰ) there is an obvious property of localization of recruitment activity, only the MNs which innervate the stimulated compartment were recruited by weaker and shorter stimuli; (ⅱ) recruitment activity spread to those MNs which supply the adjacent and distal compartments during the strength of stimulation or duration of the stimulation was increased; and (ⅲ) the recruitment property of muscle activity elicited by the local mechanical stimulation is thought similar to that of "needle feeling" along the meridian pathway during stimulation of acupuncture point.     

装修后的室内空气污染监测及控制办法

经对六安市交通大厦的监测表明，装修会引起室内空气中氨和苯系物浓度升高。而比较简便的控制办法是：选用质 量较好的石材便有可能使氡含量达标；注意改善通风条件也可在一个多月的时间里使室内氨、甲醛、苯、甲苯、二甲苯的含量达 标。     

黄石市室内空气中甲醛污染的调查与研究

分析黄石市居室空气中甲醛浓度的59个监测样本。结果表明装修后3年内，居室空气中甲醛超标率为86．4％。通过对室内甲醛污染的成因分析，得出以下结论：同一房间的甲醛含量随着温度变化。温度升高，甲醛含量会随之增高；选好装修材料，室内单位空间的甲醛含量就会低；室内装修设计时，考虑室内空间承栽量和通风量，以降低室内甲醛含量；不科学的装修工艺同样会造成室内甲醛污染。     

火车站售票厅内空气品质的检测与评价

为了解火车站售票厅内的空气质量状况,采用便携式快速检测仪于2004年7月22~30日对广州火车站售票厅内的室内空气品质进行检测.检测的参数主要有CO、CO2、可吸入颗粒物(PM10)和总挥发性有机化合物(TVOC).所测室内CO2(775~1 578×10-6)和PM10(0.129-0.346 mg.m-3)严重超标.结果表明:室内的污染水平高于室外.     

室内空气中甲醛流动注射化学发光分析

研究了没食子酸Ga—H2O2—NaOH发光体系，根据甲醛增强没食子酸发光的性质，建立了微量甲醛流动注射化学发光测定方法，并用于家庭装修室内空气中甲醛含量的环境监测．本法甲醛测定线性范围为0．01-20μg／mL，检测限为0．005μg／mL，相对标准偏差为2．1％(n=9）。     

N-terminal of L protein of vesicular stomatitis virus contains a new signal sequence

The L protein (241kD) of vesicular stomatitis virus (VSV) is the most important snbnnit of the replication complex. The existence of specific localization signal in the L protein was investigated by making recombinant constructs expressing truncated mutants of the L protein fused to green fluorescent protein (GFP) in transient transfection assays. The chimeric genes encoding varied N-terminal of L and GFP gene were put under the control of T7 promoter or CMV promoter. The fusion proteins were transiently expressed in BHK-21, COS-7, CHO or Hep G2 cells. When more than 120 residues were deleted or only 96 residues were kept on the N-terminal, the fusion proteins were shown to be distributed throughout the cells, cytoplasm and nucleus under the confocal microscope. However, other chimeric proteins with 120 or more amino acids were dotted and distributed in the perinuclear regions. And the fusion protein with 96—120 aa has the similar distribution. A thirteen-residue peptide QGYSFLHEVDKEA (108—120) was identified as localization signal, whose function would be absolutely distributed with the deficiency of D or V. Our results show that there is an independent localizing signal in N-terminal domain of L protein of VSV and this functional signal is conserved in different cell lines.
